GB/T 3369.1—2008/IEC 60381-1:1982

The standard for the 4-20mA current signal used in electric actuators is as follows: Standard: GB/T 3369.1—2008/IEC 60381-1:1982 Title: Analogue signals for process control systems — Part 1: Direct current signals (IEC 60381-1:1982, IDT) This standard defines the specifications for analog signals, specifically for the use of direct current (DC) signals in process control systems, which includes the 4-20mA current signal commonly used in electric actuators. Preface Foreword GB/T 3369 “Analog Signals for Process Control Systems” is divided into the following two parts: Part 1: Direct Current (DC) Current Signals; Part 2: DC Voltage Signals. This part is Part 1 of GB/T 3369.This part is identical to IEC 60381-1:1982, titled […]

EN15714-2 電動アクチュエータ制御（デューティ）の分類

Control Duty Classifications: Class A: ON-OFF Type (On/Off) Function: The actuator is required to drive the valve through its entire stroke from fully open to fully closed (and vice versa). Typical Use: Applications where valves are either fully open or fully closed. Class B: Fine-Tuning/Positioning Adjustment Type Function: The actuator occasionally moves the valve to any position (fully open, intermediate, or fully closed). Typical Use: Applications requiring occasional adjustment but not continuous movement. Class C: Modulating Type Function: The actuator frequently moves the valve between fully open and fully closed positions. Typical Use: Applications that require continuous and frequent modulation of valve position. Class D: Continuous Modulating Type Function: The […]

エンクロージャ保護定格（UL、CSA、NEMA）

UL、CSA、NEMAが定めるエンクロージャの保護等級は以下のように分類されています。これらの分類は一般的に類似していますが、細部には細かな違いがあるため、より正確な情報については各規格を参照することをお勧めします。タイプ分類定義 1 一般屋内用で、異常な使用環境を伴わない通常の条件下で、密閉された部品を保護する。2 防滴屋内用で、落下する水やほこりの量が制限された環境での保護。3 防雨、防塵、防みぞれ（氷）屋外用で、風による粉塵、雨、みぞれから保護します。3S 防雨、防塵、防みぞれ。

アクチュエータ IP防塵・防水等級

IP保護等級の定義IP（Ingress Protection）等級は、固形物（工具、指、ほこりなど）の侵入および水（結露、洗浄、浸水など）の浸入に対する製品の筐体の保護レベルを定義します。IP」に続く2桁の数字は、固形物および水の浸入に対する保護レベルを示します。1桁目が粉塵の保護レベルを表し、2桁目が水の保護レベルを表す。数字が大きいほど保護レベルが高くなります。例えばIP67 の場合、6 が防塵レベル、7 が防水レベルです。ダスト保護レベル番号保護範囲説明 0 保護なし [...] に対する特別な保護なし
